Maybe to simplify the process, in boost-root (where boost-build.jam file exists), we could have a makefile which automatically builds bjam from the source files and the invokes it with a given configuation.
like: make msvc (instead of bjam "-sTOOLS=msvc")
Unfortunately, I don't have any makefile knowledge.
ahhh - we've come full circle.
I am knowledgeable in makefiles, but this leads to a problem: you need to configure the makefile to handle all the various compiler and platform combinations - something bjam already handles, so why duplicate this effort?
Is there a bjam file for bjam?! That way it could be bootstrapped. But then why not just download a pre-built version of bjam?
Bascally I think the whole purpose of bjam is to address the concerns of the original poster. Unfortunately, this is not obvious from the information on bjam that comes with the system. I realise that the information is available - its just that is spread around in several places. Bjam is a large subject and requires almost a book to explain it. BUT it (or something like it is necessary for boost - as was obvious to the original poster. The central purpose of the bjam system is to specify how to build programs in a generic way independent of any particular platform while at the same time specify how each platform handles particular aspects of the application developement. This is a very ambitious concept and has resulted (not surprisingly) in a system that is pretty elaborate. A very ambitiuos effort. In one important way, its not ambitious enough. Unlike the rest of boost, it seems directed a bit narrowly to building and testing boost libraries. I get this impression from the fact that much effort is being invested in the code but relatively little in producing a complete, coherent and well organised explanation of how to make best usage of it. Maybe we can sucker someone in writing an O'Reilly book on this which would include the bjam system? Of course this would need a more polished system. I'm sorry go on about this, the thing just drives me crazy. John Torjo - bjam is exactly what you're looking for - its just not clear from the explanation. Robert Ramey
